Properties of coatings manufactured from titanium powder

The properties of coatings manufactured from titanium powder are described in this study. Coatings with thicknesses of 100 and 200 μm were deposited on a steel substrate using cumulative-detonation technology. The investigations showed the low porosity of the coatings and the absence of defects at the boundary with the substrate. Scratch tests of the coatings fixed their high adhesion and cohesion properties. Corrosion tests showed that the protective properties of the coatings are fairly high in NaCl and low in HCL. Increasing the thickness of the coatings to 0.2 mm strengthens their protective properties. Nanodispersion compounds of titanium with iron, oxygen, and carbon that decrease the corrosion resistance of the specimens in the chlorohydric acid were detected in the coatings.
